    Happened to be flipping through a baileys catalog yesterday and noticed they have a big bore kit for pretty cheap. 114 plus the gasket. Supposed to bump it up to 75 cc and be more of a torque saw than a revver. Anyone used this kit?

    Most newer 372XP's have the 75cc Piston/Cylinder already installed. I have one and the biggest different between it and the 70cc version which I've run it against is the low end torque.

    Mine's about 6 years old, 4 years it used professionally so I've been thinking about tossing a piston in anyway. This just got me thinking.
